Next time you decide to throw out an app that you no longer need, don't just throw it in the Trash – make sure that all its associated preference panes, cache, and other files are discarded as well. We normally use CleanApp for this purpose, but now you can also try the newly-minted Amnesia 1.0 from Koingo Software. It includes a secure delete option, a log of uninstalled files, a backup/restore option for applications and their related files, an option to move rather than delete files, rebuild of the Launch Services database after removing files, and other features.
